Dean, go to benzsport.com and look at the front page, there is an article written about the conversion vs oem. I know that you have the H4 bulb, but the reflectors arent really made for the xenon bulbs and so what it does is makes a lot of glare for other drivers. I know because my friend put S class bulbs and ballasts in his 190E headlights and they blind you. The article on benzsport makes a comment that OEM xenons dont hurt the eye.
No Benzes in the stable at the moment, but itching for one again.
